water.desalination+reuse March 2017 SPONSORED ARTICLE A s Az-Zour North's Phase 1 project water plant supplier, SIDEM is proud to have been involved in several firsts. First IWPP in Kuwait: In cooperation with HHI, SIDEM has built the Az-Zour North Phase 1 Independent Water and Power Plant (IWPP) in Kuwait for the benefit of Shamal Az-Zour Al-Oula, the Project Company primarily owned and managed by Engie and Sumitomo Corpora- tion. SIDEM is recognized as the best EPC contractor for large size IWPP, aˆer deliver- ing successful projects such as Ras Laffan C, Marafiq Jubail, Fujairah 2 and Al Hidd. First MED-TVC Technology Based Desali- nation Plant Units in Kuwait: Kuwait was previously relying on old MSF technology for its desalination plants but decision makers made an historical yet logi- cal move given that MED-TVC is currently the most reliable, efficient and economical tech- nology available. First MED Units in the World with Capac- ity Exceeding 10 MIGD: With an individual design capacity of 10.84 Million Imperial Gallon per Day (MIGD) and a successful test capacity of 11.5 MIGD, the Az Zour North Phase 1 MED units are now recognized as being the largest capacity units in operation worldwide. This achieve- ment sets a new industry benchmark and demonstrates SIDEM's unrivaled posi- tion as global leader in MED technology. State of the Art MED-TVC Technology Benefiting from Sidem's experience in design was engineered and provided, includ- ing high efficiency degassifiers installed downstream of limestone filters to signifi- cantly reduce caustic soda consumption. • Special care was taken for integration of the CO2 plant in the remineralization process. • A limestone filter automatic filling sys- tem using hydro carriage was engineered to improve operational conditions. • The limestone filter wash water recov- ery system results in a daily savings of approximately 5,000 m 3 of potable water. Excellence in Project Delivery Innovation and "firsts" are not possi- ble if not supported by extremely efficient project management that ultimately allows smooth project execution and on time deliv- ery of a performing plant. SIDEM's lean organization at every stage from engineer- ing to procurement, logistics, construction and commissioning was the key to Sidem's successful involvement in this project. Notable achievements include the early delivery to site of 10 fully assembled and tested MED-TVC giant evaporators (2600 tons each and 54 m long, 33 m wide, 14 m high) and the fast track commissioning with 10 units started-up in less than 5 months. SIDEM was also able to complete the reli- ability test flawlessly at the first attempt. Az -Zour North Phase 1 IWPP Main Figures • 107 MIGD Water Plant output, equiva- lent to 20% of Kuwait's drinking water production • 10 MED units, each with individual 10.84 MIGD capacity • Project executed on time in 35.5 months • 30,000 km, or 6 times the distance between Paris and Kuwait City, is the total length of MED heat exchanger tubes. Az -Zour North IWPP desalination plant supplying drinking water to Kuwait with pride SPONSORED ARTICLE the design and supply of MED units for over 40 years, the latest Az-Zour North MED plant features the world's largest and most effi- cient MED-TVC units. The MED system cur- rently under commercial operation provides a very high efficiency with a design Gain Output Ratio (GOR) of 11.2 and an actual performance-tested GOR of 12.1. Similarly, the system was performance-tested at an actual daily production of approximately 11.5 MIGD, compared to the design daily production of 10.84 MIGD. Remarkably, this performance was achieved using a very low pressure steam of 2.7 bar(a) and the MED operation is guaranteed within a wide seawater temperature range (10 to 38°C). Smart Technical Solutions for the Benefit of the Plant Owner Many innovative technical solutions were implemented for Az-Zour North Phase 1 project to minimize investment and operat- ing costs and to increase ease of operation. • A compact plant arrangement was engi- neered to minimize plant footprint, resulting in an area of less than 80,000m 2 in total. • High thermal efficiency MED units were provided based upon SIDEM's in-house kno- whow and world best TVC technology. • An optimized remineralization plant
